Name general variant of triddap
Circumradius sqrt[(a2+b2)/3]
Confer
more general variants:
case 0 < b:a < 1/2 or 2 < b:a < ∞  /  case b:a = 1/2 or b:a = 2  /  this case 1/2 < b:a < 2   with esp. case b:a = 1
general polytopal classes:
isogonal  

No uniform realisation is possible for any of those ao3ob bo3oa&#zc. Even so all are isogonal.


Incidence matrix according to Dynkin symbol

ao3ob bo3oa&#zc   → height = 0
                  1/2 < b:a < 2
                  c = sqrt[2(a2-ab+b2)/3]
(c-laced tegum sum of 2 bidual (a,b)-sized triddips)
